Leonardo DiCaprio blows off Justin Bieber

Leonardo DiCaprio may have to put up with Jonah Hill, now that Hill has become some sort of actor. But that doesn't mean he's decided to donate his time to celebrity charity cases.

According to Uproxx, a shirtless Justin Bieber spotted DiCaprio at a club during the Cannes film festival and wanted to be his friend. Which Leo wasn't having.

"Justin was strutting his stuff all over the club, walking around shirtless and scoping out chicks," a source told Star magazine. "But when he heard Leo was there, he had his bodyguard muscle a path to where Leo was sitting."

The Beebs apparently sent his guy to ask DiCaprio if he could be his pal.

"Justin was nodding and smiling in Leo's direction, but Leo just shook his head no and waved him off," a witness said. "He thinks Justin's a little twit. Leo doesn't want or need photo ops with publicity-hungry, manufactured pop stars."
